John 9:1 - 23

Jesus encounters a blind man while on His travels.  When His followers ask the source of the blindness (his own sin or the sin of his parents) Jesus' response shocks them.  The man's blindness is simply to display how great God is.  When the man's sight is restored, God gets the glory; but the man gets quite a bit of grief from the religious leaders, who think that Jesus is being self-serving.  They threaten to remove anyone who embraces or follows Jesus from worship at the temple.
